Escape key and Menu Cancel button stop working in the Marketplace home page after using the search bar

Summary:
Typing text into the Marketplace search bar in the top-right corner and submitting the search causes both the Escape key and the Menu Cancel button to stop responding on the Marketplace home page (the page shown when first opening the Marketplace). The arrow in the top-left corner still works and becomes the only way to exit.
This issue occurs only in the 1.21.130 Preview and does not occur in 1.21.124 Stable.

Steps to Reproduce:

1. Open the Marketplace.

2. Select the search bar in the top-right corner.

3. Enter any text and submit the search.

4. Exit the search results page using the Escape key or Menu Cancel button.

5. Attempt to exit the Marketplace home page using the Escape key or Menu Cancel button.

Observed Results:
The Escape key and Menu Cancel button no longer function on the Marketplace home page. The player must use the arrow in the top-left corner to exit.

Expected Results:
The Escape key and Menu Cancel button should continue to function normally after submitting a search and should allow the player to exit the Marketplace home page.
